Pugmill granulation

thyssenkrupp Industrial Solutions’ state-of-the-art technology for ammonium nitrate and CAN granulation plants. Pugmill granulation is a proprietary Uhde process, designed for maximum reliability and safety.

The heart of Uhde's proprietary pugmill granulation process is a pugmill granulator – a horizontal mixing and agglomeration device based on a U-type trough with dual shafts and paddles. Due to the speed of the paddles, the granules are fluidized in the upper part of the granulator. The recycle material and the AN melt from the ammonium nitrate neutralization plant are combined to form granules by agglomeration and layering.
